| ( | 800 | + | 1200 | ) | x | × | 22 25 | = | ( | 800 | x | × | 91 100 | ) | + | 1200 |
| Left side of the equation = | 800 | x | × | 22 25 | + | 1200 | x | × | 22 25 |
| = | 704 | x | + | 1056 | x |
| = | 1760 | x |
| 1760 | x | = | ( | 800 | x | × | 91 100 | ) | + | 1200 |
| Right side of the equation = | 800 | x | × | 91 100 | + | 1200 |
| = | 728 | x | + | 1200 |
| 1760 | x | = | 728 | x | + | 1200 |
| 1760 | x | − | 728 | x | = | 1200 |
| 1032 | x | = | 1200 |
| x | = | 1200 | ÷ | 1032 |
| = | 1200 | × | 1 1032 |
| = | 50 | × | 1 43 |
| x | = | 50 43 |
